## CAD (KiCad official)

- Symbol: `MURS220T3G-F`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `murs220t3g-f-etched.step` / `murs220t3g-f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `murs220t3g-f.step` / `murs220t3g-f.glb` are the bare package body.
